(Probability and Predictions) |
| A. Validity of data |
A1. Form and justify an opinion on whether a given statement
is reasonable based on a comparison to data. |
A1. Perform simulations with concrete devices (dice, spinner,
etc.) to predict the chance of an event occurring. |
A1. Present the results of an experiment using visual representations
(tables, charts, and graphs). |
A1. Compare odds and probability. |
|
A2. Design a fair and an unfair spinner. |
A2. Determine the fairness of a design of a spinner. |
|
A2. Determine the number of combinations and permutations for
an event. |
|
|
A3. Compare predictions based on theoretical probability and
experimental results. |
|
A3. Apply probability and statistics to perform an experiment
involving a sample and generalize its results to the entire population. |
|
|
|
|
A4. Analyze predictions such as election polls. |
|
|
|
|
A5. Draw a conclusion regarding the validity of a probability
or statistical argument and justify conclusion. |
| B. Calculating probability to make predictions |
B1. Predict and measure the likelihood of events and recognize
that the results of an experiment may not match predicted outcomes. |
B1. Predict the likely number of times a condition will occur
based on the analyzed data. |
|
B1. Compare and contrast results from observations and mathematical
models. |
|
B2. Predict the likely number of times a condition will occur
based on the analyzed data. |
B2. Express probabilities as fractions and decimals. |
|
B2. Use experimental and theoretical probability distributions
to make judgements about the likelihood of various outcomes in uncertain
situations. |
|
|
B3. Calculate the probability of a simple event. |
|
B3. Make valid inferences, predictions, and arguments based
on probability. |
|
|
B4. Determine the probability of an event involving “and”, “or”,
or “not”. |
|
B4. Solve problems involving independent simple and compound
events. |
|
|
B5. Predict and determine why some outcomes are certain, more
likely, less likely, equally likely, or impossible. |
|
|
|
|
B6. Find all possible combinations and arrangements involving
a limited number of variables. |
